What Types of Water Damage Are Most Common in Winter?

A frozen water pipe is a serious winter risk. When water inside a pipe freezes, it expands and can crack the pipe. The damage often remains hidden until the ice thaws and water flows from the break. This sudden release can flood a basement, bathroom, or kitchen, causing significant structural and content damage.

You can help prevent this by keeping your home heated and allowing faucets to drip during extreme cold. Insulating pipes in unheated areas like attics or crawl spaces is also crucial. If you plan to be away, never set your thermostat too low. Knowing the location of your main water shutoff valve is essential for stopping the flow if a pipe bursts.

Cold weather stresses water supply lines to appliances. The rubber hoses on your washing machine, refrigerator, or dishwasher can become brittle and crack in low temperatures, especially in garages or unfinished rooms. A small split can release a steady stream of water, damaging floors and cabinetry over hours or days before it's noticed.

Regularly inspect these hoses for cracks or bulges and replace them every few years. Consider upgrading to braided stainless steel supply lines, which are more durable. Check the condition of hoses in less insulated parts of your home, like a garage or unfinished room, before winter sets in. Shutting off water to appliances not in regular use adds another layer of protection.

• Washing machine supply hoses cracking under cold stress.
• Refrigerator ice maker line leaks from frozen connectors.
• Dishwasher connection failures from temperature fluctuations.
• Water heater pressure relief valve or tank corrosion.
• Sump pump discharge line freezing and causing a backup.
• Exterior hose bibs not properly drained and shut off.

Your first step is always to stop the water source if it's safe to do so. Turn off the main water valve for a burst pipe. For a roof leak, place buckets to catch water and move furniture out of the way. Then, start removing standing water and wet items to limit absorption and secondary damage like mold.

Contact local water damage pros to assess the situation. They have the tools to properly dry structures, which is more complex than it seems. Wet drywall, insulation, and flooring often need professional drying techniques. Document the damage with photos for a potential insurance claim. Policies vary, and your insurer decides what is covered.
